6  Indicator trends of priority fisheries

A fishery system is usually intersected in three perspectives—biological, harvesting and management (Figure 6.1). The biological perspective is identified by a breeding population. The harvesting business perspective is identified by fleets using comparable technologies and serving similar markets. The management perspective is identified by a common set of rules for access and harvest.

For sustainable fishery the three perspective must intersect. Several indicators are used to assess the sustainability of the fishery. In this chapter we discuss some indicators that we chose to assess the sustainability of priority fishery in the study area. Based on available data, catch rate, the composition of fished species and total fish production were chosen as metric to evaluate the health of the fishery in Kibiti, Mafia and Kilwa Seascape (Figure 6.2).

Several achieved fisheries data from government, NGO and, academia and research institutes was used to evaluate the effectiveness of management systems and help answer what works. What works best for fisheries? What works best for economic returns, business and employment? What works best for the community?
